HINGE-FORMING APPARATUS FOR METAL ARTICLES.

Application filed August 30; 1920. Serial No. 407,018.

T 0 all whom it may concern:

Be it known that I, MAGNUS E. TVIDELL, a citizen of the United States, residing in Maywood, in the county of Gook and State of Illinois, have invented a new and useful 7 tion by a single unskilled operator.

The invention has for" a further object the provision of a hinge forming apparatus that will rapidly form, or bend said lug, and this without danger of destroying the article flanges.

Another important object of the invention is the provision of an apparatus of this character requiring relatively little adjustment and devoid of delicate parts likely to require frequent repair and; replacement.

Numerous other objects and advantages of the invention will be apparent asit is better understood from the following description, which taken in connection with the accompanying drawings discloses a preferred embodiment thereof.

Referring to the drawing,

Fig. 13. is a perspective view showing the bend of the lugs.

While mypresent invention is capable of embodiment in machines having a wide variety of use, the apparatus shown on the drawing for the purpose of illustrating the invention is particularly designed to bend the hinge lugs of a box cover as indicated in Fig. 13. This cover 21 is of the ordinary type provided on tobacco boxes having the marginal flange 22 to close down over the box body and the three hinge lugs 23. These lugs are adapted to be bent from the posi tion shown in dotted lines at 24 downwardly at 25 beneath the flange 22 and then upwardly at 26 to provide the upstanding lugs offset from the body of the flange and adapt ed to be slipped behind the hinge pintle.

In the machine shown on the drawing these articles are piled on a table 31 supported upon a suitable framework 32, which framework also supports the operating mechanisms, as will be presently described. Two brackets 33 and 34 provide bearings for a power shaft carrying fast and loose of a box top pulleys 36. At the left-hand end the shaft is provided with a pulley 37 having a driving cord or belt 38 which passes around two idle pulley wheels 39 located one above the other and upon shafts a1 and the cable or belt 38 passes around a pulley 4-2 upon a shaft 43 at the left-hand end of the apparatus and this shaft also carries at the front of the machine a pulley 4 1- over which is trained a round belt or cable 4:5 taking over a front pulley 1' 5 mounted upon a stub shaft 47. The upper travel of the cable 4-5 is back of the guide 48, moving toward the right. A tensioner 51 is preferably provided also. 1

The covers 21 piled upon the table are placed by an operator in upright position upon. the belt and against the guide (Fig. 9) which carries them over toward the right of the apparatus. Above the axis of the shaft 47 of the front conveyor pulley 46 is pivotally mounted a gravity guard 52. A lug 53- extends out from a guide plate 54 at this end of the machine and the gravity guard is pivoted to this lug. It has an elongated head 55 provided with a flange 56 adapted to be disposed in front of the box tops, as may be seen in Fig. 8. A set screw 57 is positioned through the head and en gages the top of the guide 54 to maintain the guard 52 in proper position. The box tops are carried up and into posit-ion beneath the guard 52 by the conveyer belt, this occurring at the end of the operative travel of the belt.

Beyond the guard 52 are two additional uards 58 and 59 like the guard 52 and simiarly pivoted at 61 and 62 upon lugs 63 and 64 like the lugs 53 (see Figs. 6 and 7). Pressure springs 65 are provided to. pull these guards down upon the upper surfaces of the box tops and hold them firmly in the upright inclined positions shown. The pressure of these guards is sufficient to prevent the advancement of the boxes under the action of the conveyer or cable 45 and positive means are provided to intermittently advance the box tops beneath the guards 52, 58 and 59 after each hinge forming operation.

A cam 66 is fixed on the shaft 35 and is engaged by cam roll 67 upon a lever 68 pivoted at 69 in the frame of the apparatus. The forward end of this lever is provided with a slotted head 71 (Fig. 4) in which is mounted a block 72 engaging a stud or pin 73 upon a second lower block 74 located beneath the lever and indicated in dotted lines in Fig. 4. This block has also a downwardly depending pin 75 engaging in a slide 76 (Fig. 7) movable into guideways formed by the walls 77. An oscillating arm 78 is pivoted at 79 on the slide (Fig. 4) and has an operative end 81 adapted to engage behind the forward flange part of a box cover positioned beneath the guard 52. This oscillating arm is pressed by a spring 82 toward the path of travel of the box tops and its movement under the adzion of the spring is limited by a stop lug 83 engaging a pin 84 on the slide.

As has been stated the member engages behind the forward fiange part and in order that it may be positively moved to clear the box flange parts on its idle stroke I provide a control arm 85 pivoted at 86 beneath a block 87 and pressed by a spring 88 into engagement with a stop shoulder 89. The con trol 'arm 85 is provided with a cam face 91 (Fig. 12) adapted to engage a block 93 (Fig. 11) having a pin or stud 94 resting in an aperture 95 in the arm 78. On the idle stroke the block 93 engages the face 91 of the arm 85 and rides along it, moving the oscillating feeding member away from the path of the box cover. Under the pressure of the spring 82 this arm drops into feeding position when its rear clears the rear end of a cam part 96 (Fig. 12) formed on the upper side of the arm 85, the slide in this movement moving beneath the block 87. Upon the feeding stroke the upper face 97 of the block engages the rear face 98 of the control arm and moves the control arm back to permit a straight line movement of the feeding oscillating member 78 on its active stroke. The oscillating arm 78 provides positive timed intermittent advance to the box tops moving each one from beneath the guard 52 to beneath the guard 58 and said box top advancing to the guard 58 pushing the box top just previously positioned beneath this guard forwardly and under the guard 59. The hinge forming operation is accomplished beneath the last mentioned guard. The bot-- tom of the guideway here is formed into a passive female die 101 (Fig. 6) of suitable shape. An active die 102 is provided upon the end of an arm 103 pivoted at 104 in lugs 105 in the frame and pulled, by spring 106 fixed at one end of a post 107 on the frame and at the other to a post 108 on the arm, away from the passive die. The active die is caused to move on its operative stroke by a lever 109 pivoted at 111 (Fig. 5) in uprights 112 on the frame and having a roll 113 (Fig. 1) engaging in a cam slot 114 on a cam 115 on the shaft 35. This lever has a head 116 provided with a shoulder 117 ongaging upon the top of the arm 103 and pressing down to bend the lugs, as indicated in Figs. 6 and 13. The lever also is provided with a depending lug 118 having a shoulder 119 adapted to engage a pin 121 on the arm to free the dies and insure the action of the spring 106.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
